WheresMyLibrary
From The Linux Foundation
This page aims to give some pointers on libraries that are or are not in the LSB specification. Some notes on what it takes to get in are in the [http://www.linuxbase.org/futures/criteria/index.html lsb-futures selection criteria]. For a library, the "demand" criteria may not be obvious: it needs to be required for user applications. A library may be widely used, but hidden by the implementation - e.g. used by a toolkit that is in turn used by apps, but is not called directly by the app. In this case it may not need to be in the LSB. This list is neither definitive nor a roadmap of features intended to be added for any particular release, only a quick way to look up info quickly if you're curious about a library.

[edit] A Document Structure View
The LSB consists of several sets of books. Each book documents one aspect of the system. The following set of tables attempts to show which libraries are to be found in what part of the overall written specification, or where they would go if they're added. The three library columns are independent - don't read across at this point, for example there's no intended relationship between "libc", "libssl" and "libnsl" in the first data line.
